In this article I will explain with an example, how to get Output parameter from Stored Procedure using Entity Framework in ASP.Net MVC.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
 
 

Database

I have made use of the following table Customers with the schema as follows.

Stored Procedure

The following Stored Procedure will be used to Insert data into the SQL Server database table.
This Stored Procedure accepts following parameters which are used to insert the records:
Name – This is an INPUT Parameter to pass the Name of the Customer.
Country – This is an INPUT Parameter to pass the Country of the Customer.
CustomerId – This is an OUTPUT Parameter to get last inserted CustomerId.
Note: Output Parameter is identified by the keyword OUTPUT.
 
CREATE PROCEDURE [Customers_InsertCustomer_Output]
      @Name VARCHAR(100),
      @Country VARCHAR(50),
      @CustomerId INT OUTPUT
AS
BEGIN
    INSERT INTO [Customers]
               ([Name]
               ,[Country])
    VALUES
               (@Name
               ,@Country)
 
    SELECT @CustomerId =SCOPE_IDENTITY()
END
 
 

Entity Framework Model

Once the Entity Framework is configured and connected to the database table, the Model will look as shown below.
Note: For beginners in ASP.Net MVC and Entity Framework, please refer my article ASP.Net MVC: Simple Entity Framework Tutorial with example. It covers all the information needed for connecting and configuring Entity Framework.

Following Stored Procedure is imported as Function.

Note: You will notice that None option is selected, because the Stored Procedure does not return any value.
 
 

Namespaces

You will need to import the following namespace.
using System.Data.Entity.Core.Objects;
 
 

Controller

The Controller consists of following Action methods.

Action method for handling GET operation

Inside this Action method, simply the View is returned.
 

Action method for handling POST operation

This method accepts Customer class object as a parameter.
Inside this Action method, an object of AjaxSamplesEntities is created and ObjectParameter class for CustomerId is initiated.
The Stored Procedure is called using Entity Framework and Name, Country and an ObjectParameter i.e. CustomerId are passed as parameters.
Then, the inserted CustomerId is fetched from the ObjectParameter value.
Finally, the CustomerId of the inserted record is set and the Customer class object is returned to the View.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Index(Customer customer)
    {
        using (AjaxSamplesEntities entities = new AjaxSamplesEntities())
        {
            ObjectParameter param = new ObjectParameter("CustomerId", typeof(int));
            entities.Customers_InsertCustomer_Output(customer.Name, customer.Country, param);
            customer.CustomerId = Convert.ToInt32(param.Value);
        }
 
        return View(customer);
    }
}
 
 

View

HTML Markup

Inside the View, in the very first line the Customer class is declared as Model for the View.
The View consists of an HTML Form which has been created using the Html.BeginForm method with the following parameters.
ActionName – Name of the Action. In this case the name is Index.
ControllerName – Name of the Controller. In this case the name is Home.
FormMethod – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
The View also consists of an HTML Table, which consists of TextBox and DropDownList created using Html.TextBoxFor and HTML.DropDownListFor methods respectively and a Submit button.
Inside the View, the following script file is inherited:
1. jquery.min.js
 

Submitting the Form

When the Submit button is clicked then, the Model is checked for NULL and if it is not NULL then, the CustomerId is displayed using JavaScript Alert Message Box.
@model Customer
@{
    Layout = null;
}
 
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    @using (Html.BeginForm("Index", "Home", FormMethod.Post))
    {
        <table cellpadding="0" cellspacing="0">
            <tr>
                <td>Name: </td>
                <td>
                    @Html.TextBoxFor(m => m.Name)
                </td>
            </tr>
            <tr>
                <td>Country: </td>
                <td>
                    @Html.DropDownListFor(m => m.Country, new List<SelectListItem>
                    {
                      new SelectListItem { Text = "United States", Value = "United States" },
                      new SelectListItem { Text = "India", Value = "India" },
                      new SelectListItem { Text = "France", Value = "France" },
                      new SelectListItem { Text = "Russia", Value = "Russia" }}, "Please select")
                </td>
            </tr>
            <tr>
                <td></td>
                <td><input type="submit" value="Submit" /></td>
            </tr>
        </table>
    }
    <script type="text/javascript"src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
    @if (Model != null)
    {
        <script type="text/javascript">
            $(function () {
                alert("Inserted Customer ID: " + @Model.CustomerId);
            });
        </script>
    }
</body>
</html>
